Drywall dust causes scare that shuts down Yorkville health office

Staff report

The Kendall County Health Department's office in Yorkville was closed for about two hours when a worker discovered an envelope containing white powder. The substance was later determined to be drywall dust.

The building at 811 W. John St. was evacuated around 11:15 a.m. after the envelope was found among office supplies in a secure area. Officials said they determined that the power was drywall dust that came from a nearby construction area.
